DEVICE FOR ROLLING STRIPS OF MATERIAL.

Specification of Letters Patent.

Patented Dec. 24, 1918.

Application filed Gctober 26. 1917. Serial No. 198,714.

To (all whom, it may concer/n:

Be it known that I, HUGH KERK THoMAs, a subject of the King of Great Britain', residing at Buffalo, in the county of 'Erie and State of New York, have invented a new and useful improvement in Devices for Rolling Strips of Material, of which the following is a specification. i

r1`his invention relates to a device for rolling, or winding into rolls, strips of material, such, for instance, `as surgical bandages.

The object of the invention is to provide a simple and inexpensive device for this pur pose which can be readily placed in condition for use and easily operated to quickly and evenly roll the bandages or strips.

In the accompanying drawings Figure 1 is a side elevation of a strip rolling or winding device embodying the inven tion.

Fig. 2 is an end elevation thereof.

Fig. 3 is an elevation ofthe opposite side of the frame for the winding shaft, removed from the supporting table.

Fig. el is an elevation of the winding shaft, one of the strip guide disks being removed therefrom and the split portion of the shaft being sprung open ready to receive the end of the strip.

A represents a rotatable winding shaft which is rotatably supported, preferably at its opposite ends, in a suitable frame or support, which, as shown consists of bearings B fixed to and rising from a base plate or board C. Preferably, the shaft rests loosely in bearing seats or notches -10 in the bearings B `and is removably retained therein by suitable means, such for example as bearing caps or keepers 11 which are pivoted by screws 12, on the upper ends of the bearings so that they can swing horizontally to and from retaining positions over the ends of the shaft. The shaft can be readily removed from its bearings by swinging the caps or keepers 11 outwardly and lifting the shaft out of its bearing seats. The shaft A is split lengthwise from one end thereof, or has two parts 13 which are adapted to spring apart, as shown in Fig. 4., or to be separated to enable the end of the strip of material to be wound to be readily slipped in between the parts of the shaft.

lei and 15 indicate two circular disks or confining members which are secured on the winding shaft A for confining and guiding the strip between them as the strip is being wound on the shaft. These disks are securedlon the shaft in any convenient way adapting them to 'be adjusted toward and from each other to accommodate strips or bandages of different widths. Preferably, each disk is provided with a hub 16 through which the shaft loosely passes and the disks are .secured on the shaft by set screws 17 passing through the hubs 16 of the disk. These set screws are preferably long and eX- tend to or beyond the periphery of the disks so thatthey can be readily turned for releasing and securing the disks. The disk 15 holds the free ends of the parts of the split shaft together and when it is desired to attach the end of the strip or bandage to the shaft, this disk is slipped off of the shaft and the end of the strip is inserted between the parts of the shaft. The disk 15 is then slipped on to the Vshaft again and secured in a proper position. The shaft is provided at one end with a suitable crank or handle 18 for turning it.

The frame in which the winding shaft is journaled is preferably adapted to be removably retained in place on an ordinary table or analogous suitable support 19, for which purpose the base plate or board C of the frame has secured to it strtips or members 20 provided at their ends with hooks 21 adapte-d to embrace one end of the table 19 to hold the frame stationary and prevent it from being moved alon the table top.

22 indicates a guide rollr for the strip or bandage. This roller, as shown, is journaled at its ends in holes in the upper ends of two bearing plates or strips 23 which are secured to and extend upwardly from one edge of the base plate Cof the frame. The strip or bandage passes under this guide roller between the bearings therefor.

ln order to hold the strip yor .bandage under suitable tensionl while it is being wound on the shaft A, the free end of the former is preferably engaged with a clip2i of any suit-able construction which is arranged to slide toward and from the winding shaft i on the table top and is connected to suitable tensioning means consisting, for instance, of a cord or flexible connectionl25 which eX- tends from the clip under a pulley 26 and over a pulley 27 and is provided at its free end with a weight 28 which tends to draw the clip away from the winding shaft and hold the strip under tension. The pulleys 26 and 27 for the tension cord are mounted on a suitable standard or support arranged at the end of the table opposite to that at which the winding shaft and its supporting frame are located. This support can be secured in place in any suitable manner, as for instance by means of a hooked plate or clip 29 which is secured to the pulley support and is adapted to embrace the end of the table.

In the operation of the device one end of the strip or bandage'is secured between the parts of the split winding shaft A in the manner explained. The disk 15 is then slipped on the shaft'and secured and the shaft is placed in its bearing seats and the caps or keepers 11 turned to retain the shaft in the bearing seats. The opposite end of the strip is then attached to the tension clip 24 and the shaft A is rotated to wind the strip thereon. When the strip has been wound into a roll on the shaft, the shaft is removed from its bearings and withdrawn from the roll of material and another strip attached t0 the shaft and to the tension clip ready to be wound. In this way the strips or bandages can be very quickly and evenly wound into rolls. IVhen the strip is attached to the winding shaft and tension clip it is held under tension and tends to hold the Winding frame and the ytensioning device in engagement with the opposite ends of thc table and prevent the displacement of the parts during the use of the device.

I claim as my invention:

1. In a device for winding strips of matcrial into rolls, the combination of a winding shaft formed of a single round rod which is split lengthwise froin one end along the aXis thereof, forming parts having` a normal tendency to spring apart to permit the insertion of the strip between them, means for holding said shaft parts from separation, and means for rotatably supporting said shaft.

2. In a device for winding strips 0f material into rolls, the combination of a winding' shaft having separable longitudinal parts between which the strip is adapted to be inserted and held, confining disks for the strip secured on said shaft at opposite sides of the Strip for guiding the strip while being wound, one of said disks holding the parts of the shaft from separation and being removable to allow the separation of the shaft parts, and means for rotatably supporting said shaft.

3. In a device for winding strips 0f material into rolls, the combination of a winding` shaft formed 0f a single rod which is split lengthwise from one end forming parts having a normal tendency to spring apart to permit the insertion of the strip between them, confining members which are adjustable to and from each other on said shaft and are secured on said shaft at opposite sides of the strip and one of which is removable to allow the separation of the shaft parts, and bearings in which said shaft vis rotatably and removably retained.

4. In a device for winding strips of material into rolls, the combination of a winding shaft having means for attaching one end of the strip thereto, a frame in which said shaft is rotatably journaled and which is provided with a member adapted to be hooked over the edge of a support for removably retaining the frame on the support, and tensioning means for the strip which eXert tension on the strip in a direction to.

hold said retaining member in retaining engagement with said support.

5. In a device for winding strips of material into rolls, the combination of a winding shaft having means for` attaching one end of the strip thereto, a frame in which said shaft is rotatably journaled and which is adapted to rest 0n a support and is provided with a member arranged to engage said support for removably retaining the frame in place on the support, a clip which is attached to the opposite end ofthe strip and isl arranged to move along said support, and means connected to said clip Yfor holding the strip under tension and thereby holding said frame member in retaining engagement with said support. l
